Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The requirements and specification of a protocol for low level communication between the run-time systems in a distributed Ada environment is presented. This allows an Ada system to be separated into software resources and run-time controllers. Calls to the local run-time system of a node, concerning task management, are transformed into remote calls to the controller, that schedules all tasks in the application. The calls to the run-time system together with all messages, requests and replies, that are triggered as a consequence, are described. The controller will be implemented in hardware separate from the processors. Communication between processors and controllers are by means of high speed (Gigabit) networks. In the proposed system, partitioning and distribution of Ada programs can fully utilize the inherent and strong type checking in Ada.

Distribution of Tasks Within a Centrally Scheduled Local Area Network
- 1994

Ingår i: Proc. Ada-Europe'94, LNCS 887. - Berlin, Heidelberg : Springer Berlin Heidelberg. ; , s. 421-432

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Distribution of a single Ada program on a local area network is accomplished by partitioning the run-time system into two parts. A central scheduling module is responsible for task management. Distributed run-time executives handle context switches and remote entry calls; however all activities are supervised by the scheduler. The scheduler can be implemented in hardware in order to achieve high efficiency. A network based on optical fibers is necessary due to the high speed required for system calls. Asynchronous Transfer Mode is suggested as the protocol for the communication. We describe an implementation of the divided run-time system on an Ethernet network, using MC68030-based micro computers as targets and an Ada program executing on a Rational host as the scheduler.

Are there still Social Inequalities in Height and Body Mass Index of Stockholm Children
- 1994
-
Ingår i: Scandinavian Journal of Social Medicine. - 0300-8037. ; 22:3, s. 161-165
-
Tidskriftsartikel (refereegranskat)abstract
- Height and body mass index (BMI) of all non-immigrant schoolchildren in Stockholm in the age interval 10.0-10.9 years born in 1981 were related to the mother's educational level and the number of siblings. The two social variables were dichotomized and two extreme groups of socially more and less privileged children were formed. Socially less privileged boys were 1.1 cm shorter than their more privileged peers, whereas there was no difference as regards girls. Socially less privileged children were expected to show higher BMI, but the finding was contrary. More privileged boys were heavier. The findings were compared to a previous study of Stockholm children born in 1933-1963. Major social inequalities in height were levelled out for Stockholm children in the 1950s, a social gap reappeared in the 1960s and small disparities still exist for boys today.

Differences in Height between Socially more and less privileged 10 year old Stockholm Children born in 1933-1963
- 1992
-
Ingår i: Scandinavian Journal of Social Medicine. - 0300-8037. ; 20:1, s. 5-10
-
Tidskriftsartikel (refereegranskat)abstract
- The change of the difference in height between two socially extreme groups of 10 year old Stockholm children born in 1933, 1943, 1953 and 1963 was analysed. Data on height and social conditions were taken from the school health records. The two groups were established on the basis of the father's occupation and the number of children in the family. The height of the 10 year old children in the more privileged group born in 1933, 1943 and 1953 was virtually unchanged, but the height in the less privileged group increased gradually. The difference between the two groups was levelled out in the 1953 cohort. However, it reappeared in the 1963 cohort, mainly as a result of increasing height in the more privileged group and fairly unchanged height in the less privileged group.

Growth Data in the School Health Service: an indicator of public health? A Nordic review
- 1991
-
Ingår i: European Journal of Public Health. - : Oxford University Press (OUP). - 1101-1262 .- 1464-360X. ; 1:2, s. 100-104
-
Tidskriftsartikel (refereegranskat)abstract
- Monitoring the height and weight of school children is a standard procedure in Nordic schools. These data are used for individual assessments of health and for the development and revision of growth standards. Growth data born previous Nordic studies are analysed. Secular charges in height and weight are described. The usefulness of height as an indicator of social inequality is discussed. The mean height of 10 year old Nordic children increased about 1 cm per decade since the 1930s. There were considerable differences in children's mean height among the five Nordic countries and among children of different socio-economic conditions. The studies of height and weight of Nordic school children differ too much in design to allow closer analyses. Systematic time series studies of growth data from the school health service to assess secular changes in growth and changes of social inequalities are desirable.
